Slightly less messy patch. It uses the main memory rather than the SD card. Again, make sure you have an appropriate layout (a partition of type 0 somewhere) and the iPod_Control directory.

I've been unable to copy AAC files to my Sansa with this, but I'm fairly sure that's because I removed AAC support from the XML at one point and iTunes remembers this. I doubt this'll be a problem for anyone else.
